Structure and bonding

Question 1

What is the difference between covalent and ionic bonds

Answer 1

A covalent bond is between 2 non-metals so they share electrons to gain full outer shells and become compounds

An ionic bond is between a metal and a non-metal. The metal loses an electron to become positively charged and the non-metal gains an electron to become negatively charged.

Question 2

What do the groups of the periodic table tell us

Answer 2

How many electrons are in the outer shell

Question 3

The ratio of metals to non-metals in an ionic bond deters what

Answer 3

The symbol equation

NaCl or Sa2O

Question 4

What does the structure of an ionic bond look like

Answer 4

Large, regular, like marbles in a box

Question 5

What are bonds like in an ionic structure

Answer 5

Strong electrostatic forces of attraction, each atom of held up by being surrounded by the opposing force

Question 6

What is a macromolecule

Answer 6

A very large covalent bond, known as a giant structure

Question 7

Metallic bonding characteristics

Answer 7

Atoms are the same size
Arranged in regular patterns
When metals pack together the outer electrons delocalise and can move freely which produces a lattice that attracts the positive ions and holds the structure together
